FIREPROOF PAINT.

N Drawing. Application filed June 14, 1923, Serial No. 645,341. Renewed May 26, 1926.

The invention relates to paints and has as an object the provision of a fire proof paint which shall be absolutely non-inflammable.

A further object of the invention is the provision of a paint which will not only protect the material to which it is applied from fire but will also be effective to perform the usual function of paint by protecting the material to which it is applied from the effects of weather or wear.

A further object of the invention is the provision of paint which is applicable not only to wood but to paper and all other inflammable materials. A further object of the invention is the provision of a paint which will have a high gloss which is not affected by the action of the elements. The formula which is preferred as a physical embodiment of the invention comprisesthe following ingredients in the proportlons named Thinner (No. 3)

The thinner listed in the above formula is made the subject matter of a separate application, Serial No. 645,346 filed June 14, 1923, the formula of which is as follows:

Parts Nearturps 4O Turpentine Zinc sulphate 5 Hexachlorethane 1 Drying oil 4 Carbon tetrachloride 4Q In the formula for the paint above given zinc white is listed which it is preferred to use as being resistant to fumes particularly of ammonia. It will be understood that white lead may be substituted for this ma tcrial'if so desired.

By the term Nearturps used in the above formula, a hydrocarbon is referred to which is a gasoline produced by a straight distillation process and which has been deodorized by treatment with alcohol.

The silica or kaolin in the above formula is utilized as an inert filler and may be replaced by many other materials in finely divided condition which are sufiiciently inexpensive and which are inert. Because of their cheapness many forms of earthy material may be desirably used. While a small proportion of thinner is recited, it will be understood that if the paint has the desired consistency without the thinner the same may be omitted without detriment to the fireproof qualities of the paint.

Minor changes may be made in the proportions of parts and known equivalents may be substituted for some of the ingredients named without departing from the spirit of the invention.

I claim:

1. A fireproof paint comprising in combination, drying oil, zinc white, lead sulphate, lead carbonate, finely divided inert filling material, borax, potash alum, boric acid, tungstate of sodium and a thinner in proportions to produce a fire-proof paint.

2. A fireproof paint comprising in com bination, drying oil, 75 parts, zinc white, 40 parts, lead sulphate, parts, lead carbonate, 20 parts, inert filling material, 10 parts, borax, 10 parts, potash alum, 10 parts, boric acid, 5 parts and tungstate of sodium, 5 parts.

3. A fireproof paint comprising in combination, drying oil, 75 parts, zinc White, parts, lead sulphate, 20 parts, lead carbonate, 20 parts, inert filling material, 10 parts, borax, 10 parts, potash alum, 10 parts, boric acid, 5 parts, tungstate of sodium, 5 parts, and 5 parts of a thinner comprising N earturps, 40 parts, turpentine, 10 parts, zinc sulphate, 5 parts, hexachlorethane, 1 part, drying oil, 4 parts and carbon tetrachloride, 40 parts.
